We have the swiss pass along with family card. Which option on the following page would we need to choose, assuming we are starting in Wengen? Would it be the Jungfraujoch, or does it have to be the Good Morning/afternoon ticket?

Thank you. So, would we just need the jungfrau option of 163.00 on that price page? I assume we would get the 25% discount? Why is there a one-way option to jungfrau? Can you come back a different way?

Just to add...........If we have a family card with our Swiss Passes for our 14 and 15 year olds, do they get to travel to Jungfrau for free? I know they do to Grindelwald, but do they actually get all the way up to the top of Jungfrau for free?

Yes, you need the Jungfrau option, you'll get a 25% discount, and the children travel for free all the way.

You can travel back via Grindelwald. See the Jungfraujoch page Annika linked to for route details. It's one ticket for the entire route. Just ask for a ticket to the Jungfrau and back to Wengen via Grindelwald.
